Battery Level Indication

With the light switched off, single click the switch to check the battery status. The battery level indicator will display the battery status for 3 seconds.

  • Green constant on: saturated (100% – 70%)
  • Green flashes: sufficient (70% – 40%)
  • Red constant on: poor (40% – 10%)
  • Red flashes (2Hz): critical (10% – 1%)
  • Note: The battery status will be displayed each time the light is switched on.

Intelligent Protection

The light will accumulate a lot of heat when used on High output level for extended periods. To reduce the temperature, the light will automatically step down a few lumens. High output level can be reselected if needed.

Low-Voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens on Eco output mode, the battery level indicator blinks red to remind you to recharge the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery is depleted.
